Is it possible to make a circular NSButton?
NSButton is a subclass of NSView, so all methods in NSView, such as drawRect(_:), are also available in NSButton.
So create a new Button.swift which you draw your custom layout
import Cocoa
class Button: NSButton {
override func drawRect(dirtyRect: NSRect) {
super.drawRect(dirtyRect)
// Drawing code here.
let path = NSBezierPath(ovalIn: dirtyRect)
NSColor.green.setFill()
path.fill()
}
}
Great Tutorial Here. It is iOS , but quite similar!
Don't play around with corner radius. A circle doesn't have corners. To make the button appear as a circle, mask the button's layer
to a circle.
You are setting the radius based upon the width of the button. By the look of your screenshot, the button is not a square when you start, so rounding the corners cannot create a circle.
